Re: Convenient way to use 5.10 features in perldebugger?

[james2vegas]

Or,

1. copy perl5db.pl from your PERL5LIB to either somewhere in PERL5LIB or the current directory, with a different name, say myperl5db.pl
2. Edit myperl5db.pl to have use feature ':5.10'; (or just 'state', or just 'say') on the first line.
3. Set the environment variable PERL5DB to "BEGIN { require 'myperl5db.pl' }"

Now perl -de0 will let you the new features.

Thanks, good suggestion to generally enable all features! :)

Actually I was looking for a switch to change interactively on demand, which doesn't include changing the source ... still grateful for any suggestions! :)

[james2vegas]

Well, it isn't really changing the source, just having a local version of it, and if you have it in your PERL5LIB, enabling or disabling it is just a matter of setting or unsetting PERL5DB. Also worth noting is this is not limited to just enabling 'features' but you can add modules you use a lot in debugging (Data::Dumper, YAML, JSON, etc), or subs you write yourself.

I really appreciate your suggestion, but don't you think there should be an easier approach?

And if not shouldn't it be a feature request?

I tried to experiment with the < command but it seems I don't really understand how they work ...
